AI search optimization and GEO: getting cited by ChatGPT, Perplexity and Google AI Overviews
Generative engine optimization: the natural extension of SEO for biotech, medtech and deeptech companies
- ChatGPT, Perplexity, Gemini and Google AI Overviews
- AI visibility diagnosis on your key questions
- Clear entity and citable content
- Monthly citation tracking with the AI Marketing Studio
AI search optimization, or GEO (Generative Engine Optimization), covers all the actions that allow a company to be picked up and cited in the answers of AI assistants: ChatGPT, Perplexity, Gemini and Google's AI Overviews. Where SEO seeks a position in a list of links, GEO seeks a place in a written answer.
For a scientific company, the stake is concrete: investors, partners and buyers increasingly ask an assistant which companies exist in a category. If you are not there, you do not exist for them.

How answer engines choose their sources
An AI assistant answering a business question runs several searches, reads the pages that answer most directly, and retains the companies whose identity is clear: who they are, what they do, for whom, where, with what evidence. It favors structured pages, sharp definitions, questions and answers, sourced data and third-party corroboration (directories, partners, press, reviews).
The fundamentals are the same as SEO: useful content, demonstrated expertise, structured data, authority. GEO adds a requirement of readability and consistency of the entity across every channel.
What we do for your visibility in AI engines
Diagnosis: which questions your audiences ask AI engines, who is cited today, and why not you
Clear entity: explicit About and service pages, Organization and Service structured data, llms.txt file, consistent information on LinkedIn, Google Business and directories
Citable content: pages that answer a precise question, structured FAQs, definitions, sourced data, detailed case studies
Corroboration: visible partnerships, mentions in the ecosystem, reviews and testimonials
Measurement: monthly tracking of your citations in ChatGPT, Perplexity and Google AI Overviews with the AI Marketing Studio
Where does your visibility stand in ChatGPT and Perplexity?
A diagnosis on the questions your prospects ask shows who is cited in your place and which pages are missing.
GEO and SEO: the same work, two results
Content designed to be cited by an AI engine is also content that ranks well on Google: clear structure, direct answer, sources, identified expertise. So we handle both together, with a single content plan and a single dashboard. What changes is the measurement: alongside the Google ranking comes the share of AI answers in which you appear.
GEO SEO: what the numbers say
The vocabulary is settling. In France, "geo seo" is searched 2,900 times a month, "agence geo" 1,600 times, "generative engine optimization" 880 times and "référencement ia" 390 times (DataForSEO, August 2026). Three expressions for one discipline: optimising your presence in generated answers, alongside search engine optimisation.
What changes for a scientific company is the measurement. Next to Google rankings comes the share of AI answers in which it is cited, question by question, engine by engine. This is the indicator we track every month, and the one our GEO agency service takes care of end to end.
What is specific to scientific sectors
AI engines are cautious on health and technical subjects: they more readily pick up sources that explain without exaggerating and that respect the regulatory framework. Scientific rigor, often seen as a marketing handicap, becomes an advantage here. Our MD and PhD writers produce content that AI engines can cite without distorting it.
Where to start
The first step is an AI visibility diagnosis on the questions your prospects ask. It shows where you stand, who is cited in your place and which pages are missing. It leads to a content and corroboration plan that we implement and measure every month.

Frequently asked questions
What is GEO?
GEO, for Generative Engine Optimization, covers the actions that allow a company to be picked up and cited in the answers of AI assistants such as ChatGPT, Perplexity, Gemini or Google's AI Overviews. It is also called AI search optimization.
Does AI search optimization replace SEO?
No, it extends it. AI assistants rely on the same signals as Google: useful content, expertise, structure, authority. Good SEO work is the foundation; GEO adds clarity of the entity and content designed to be cited.
How do I know whether my company is cited by AI engines?
By asking the assistants the questions your prospects ask and tracking the answers over time. Our AI Marketing Studio automates this tracking on ChatGPT, Perplexity and Google AI Overviews.
How long does it take to appear in AI answers?
The first effects often appear within a few weeks for engines that read the web in real time, such as Perplexity, and over several months for the others. Regularity and external corroboration make the difference.
Is it suited to a biotech or a medtech?
Particularly so. AI engines favor rigorous, careful sources on scientific and health subjects. A company that explains its science well, with evidence, starts with an advantage.
